Friends young son getting an IRN

Hi there,

One of my friends is getting a baby IRN tomorrow for his 10yr old son, his son has been asking questions for months and has read up a huge amount on looking after birds.
He is going to take my advice still though, ive never had a baby bird so not too sure on the process of bringing it home. Im assuming I talk to the breeder and ask what the current diet is (correct if needed), also ask the breeder on tameness and levels of handling the young bird is used to. Also assuming when brought home the bird should be allowed a day or two in the cage to acclimatise to his new surroundings and humans. Humans talk/read to the new bird as much as possible from a distance that the bird feels safe with (body language)

After this 'break in' period, try and teach step up etc and take it from there?

I realise IRN can quickly go wild without interaction and training, so what is an acceptable time per day for interactions?

Sorry to bombard you, but the better start his son gets the better/happier the new flock will be.

Thanks guys :)
